18V-332May 17, 2018
Electrical System:Wiring

Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles. These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating.

Risk and remedy
Risk: If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.
Remedy: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. The recall began June 4, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed. In the event that cruise control cannot be disengaged while driving, owners should firmly and steadily apply the brakes and shift the transmission to neutral, placing the vehicle in park once it has stopped.

Totally integrated power module failure. Closed jul 24, 2015.

NHTSA summary
In a letter dated August 21, 2014, the Center for Auto Safety (CAS) petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a defect investigation of alleged failures associated with the Totally Integrated Power Module (TIPM) installed in Chrysler SUV?s, trucks, and vans beginning in the 2007 model year. The petitioner alleges that TIPM defects may result in engine stall, airbag non-deployment, failure of fuel pump shutoff resulting in unintended acceleration, fire, and other symptoms. On September 25, 2014, the Office of Defects Investigation (ODI) opened DP14-004 to evaluate the petition for a grant or deny decision. ODI analyzed complaint data provided by CAS as well as complaints submitted to ODI from consumers. In total, there were 296 complaints submitted by the petitioner in the original petition and five supplements, including 271 complaints related to the subject vehicles equipped with TIPM-7. Approximately 3 percent of CAS complaints are related to vehicles equipped with TIPM-6 and ODI?s review of these complaints did not identify any safety defect trends. ODI conducted a detailed review of complaints narratives submitted by CAS and consumers including careful analysis of vehicle repair histories, warranty claims obtained from the manufacturer and any available Customer Assistance Inquiry reports (CAIR). Analysis of the field data indicated that MY2011-2013 Jeep Grand Cherokee and Dodge Durango vehicles exhibited significantly higher compla

Headliner fires. Closed aug 12, 2014, led to recall 14V-391.

NHTSA summary
On July 1st, 2014 Chrysler Group LLC (Chrysler) notified the Office of Defects Investigation (ODI) that it would conduct a safety recall to remedy a wiring-related fire hazard on the headliner of approximately 661,888 model year (MY) 2011-2014 Jeep Grand Cherokee and Dodge Durango vehicles manufactured between January 5, 2010 and December 11, 2013 (see NHTSA Safety Recall 14V-391), with notifications to begin in August 2014. According to Chrysler, the fire is caused by an electrical short in the vanity lamp wiring for either one of the sun visors mounted on the vehicle. The sun visors are mounted to the roof of the vehicle through the headliner with three metal screws. It is possible for the sun visor wiring to be pierced by one of these screws either during initial vehicle assembly or later headliner area repairs which may cause an electrical short potentially resulting in fire.ODI opened an investigation involving MY 2011-2013 Jeep Grand Cherokee and Dodge Durango vehicles based on consumer reports of headliners catching fire at the front of the passenger's compartment near the sun visors. Complainants reported failure symptoms that ranged from discoloration to open flame burning of the headliner and/or sun visor material. Complainants reported a burning plastic smell and smoke from the headliner, often occurring while the vehicle was in motion. Damage ranged from a small burn spot on the headliner to a near complete burn of the vehicle resulting in a total loss; sunroof da

Headliner fires. Closed jan 14, 2014.

NHTSA summary
The Office of Defects Investigation (ODI) has identified 5 reports of vehicle headliners catching fire at the front of the vehicle near the sun visors on Jeep Grand Cherokees.Customers reported a range of fire conditions ranging from minor overheating to an open flame at the headliner and/or sun visor material while driving the vehicle. In some reports the fire spread to the front seats and/or door panels of the vehicle.In one report, the sunroof was damaged causing the glass to shatter.The cause of these fires is an electrical short in the vanity lighting wiring circuit that is routed to either one of the sun visors.The sun visors are mounted to the roof of the vehicle through the headliner with three screws.The sun visor wiring may be penetrated, or pierced by one of these screws either during initial vehicle assembly or subsequent headliner area repairs.The piercing causes an electrical short that could result in a fire.There is no dedicated fuse for the affected circuit so the electrical short can continue until the short clears or the vehicle is keyed off.The Dodge Durango uses the same headliner assembly, and Chrysler indicates there are similar headliner fire incidents affecting this model. Therefore, these vehicles have been added to the scope of the investigation.Analyzing the data received from Chrysler along with ODI reports indicates there may be a total of 52 unique fire incidents (including 3 injury allegations) on Grand Cherokee and Durango vehicles which ODI w

What owners wrote

“Battery drain. Two (2) new batteries installed Aux and Main battery bought/installed February 2024. I am still having battery drainage issues.”

Filed Aug 23, 2024

“I replaced the auxiliary battery, the main battery and the alternator, and my car is still losing power. I think that the voltage regulator that regulates how much power the battery gets is the actual issue. My car was manufactured in October 2017. Why wasn’t it apart of the original recall? I want this fixed. I shouldn’t have had to shell this money out when it’s a manufacturer’s defect.”

Filed May 28, 2024

“Auxiliary battery which manages auto start/stop fails. First time battery was tested and replaced under warranty. Failed again two years later - out of warranty. Unsure about risk but depending on who you ask, the failed auxiliary battery can be a parasite to the main battery, leading to potential breakdown. Also misleading fuel consumption numbers due to auto start/stop not functioning”
